Q235 steel is a carbon structural steel. It is equivalent to A3 and C3 steel in the old standard GB700-79 grade, and it is the grade of Russian TOCT. The Q in the steel number represents the yield strength. Usually, the steel is used directly without heat treatment.

Corrosion Inhibition of Q235 Mild Steel in 0.5 M H2SO4 The inhibition properties of phytic acid (PA) on Q235 mild steel corrosion in 0.5 M H 2 SO 4 was estimated using electrochemical techniques. Polarization results revealed PA to be a mixed-type inhibitor in 0.5 M H 2 SO 4, with a more pronounced cathodic effect, while impedance results indicate adsorption of the PA species on the steel surface.The values of the synergistic factor with KI were
Mar 01, 2019 · Thalassospira sp. is an iron-reducing bacterium isolated from the marine environment. Effects of T. sp. on corrosion behaviors of Q235 carbon steel in air-saturated seawater were studied.Results of electrochemical measurements and weight loss indicated that the presence of T. sp. promotes Q235 carbon steel corrosion.Surface analyses results showed that heterogeneous Frontiers Corrosion of Q235 Carbon Steel in Seawater Iron-oxidizing bacteria (IOB) and iron-reducing bacteria (IRB) can easily adhere onto carbon steel surface to form biofilm and affect corrosion processes. However, the mechanism of mixed consortium induced carbon steel corrosion is relatively underexplored. In this paper, the adsorptions of IOB (Mariprofundus ferrooxydans, M. f.), IRB (Thalassospira sp., T. sp.) and mixed consortium (M. f. and
